Sure, I can't guarantee any significant time commitment, but this would
serve as a good CL learning experience for me, so count me as /on board/
to help to port cl-heresy to elisp.

As a first step, I've copied the latest release of cl-heresy into a git
repository on repo.or.cz [1].  Anyone can anonymously push to the mob
branch of this repo (see [2]), and anyone who's interested in helping
can send me their repo.or.cz username and I'll grant push permission for
the master branch.

Best -- Eric
